PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 394,757, dated December 18, 1888.

Application led July I3, 1887. Serial No. 244,222. (No specimens.)

To @ZZ wlw/1t t may concern.'

Beit known that I, RICHARD A. COONEY, a citizen ot' the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Paper Bags; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being' had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in paper bags, the object being to provide a bag' of simple construction, that will obviate the necessity of bending' or crimping the lower corners in order to keep the same open 5 and with this end in view my invention consists in certain details ot' construction, as will be fully described hereinafter.

In the accompanying' drawings, Figure lis a diagram ot' the blank cut and formed in accordance with my invention. Fig. 2 isaI perspective view of one of my improved paper bags, designed to show the folds or laps formed on the base. of the same. Fig. 3 is a perspective view ot' the same part-ly folded for packing'. Fig. a is a perspective View of the bag open, ready for use. Fig. 5 is a diagram of the base, showing the diagonal lines of folding the same.

To put my invention into practice, I cut from paper a blank, c., having a central projecting' portion, l), and two smaller projecting parts, c, arranged along on one side of the blank, one of the end portions or iiaps, c, being arranged at each end of the blank, while the larger portion or flap, o, is arranged midway between said end flaps or portions on the same side of the blank. A creasing-line, d, is formed longitudinally of the blank in rear of the end and middle flaps, and between the middle flap, l), and each end flap, c, is formed a narrow re-enforcing strip, f, which is made by cutting the blank inwardly to the longitudinal creasing-line d, these cuts f being parallel to the edges of the flaps, as clearly shown in Fig'. l. The blank is further scored or creased transversely, as at g g g2 g3, which are arranged at right angles to the longitudi- 5o nal creasing-line d.

IVith a blank prepared as described the method of making the bag is as follows: The blank is bent or folded transversely on the score-lines g g g2 g3, and the edges e thereof 55 are lapped and cemented together, which forms a rectangular open-end box or bag, having' at one end the projecting' flaps b c. The two smaller flaps, c c, on one of the sides of the bag are now folded at right angles to the bag 6c across one of the open ends thereof, and these smaller flaps are cemented together' to form one-half of the base of the bag'. The larger flap, Z), is nowfolded at right angles to the bag, so that it overlaps the previously united flaps c c, to which it is cemented, and the strips f (which lie within the base of the bag formed by the united iiaps o c c) are now cemented to the iiaps to eftectually close the joints between the side edges of the bag and the iiaps. 7o

It will be noted that the flap l) is integral with one side of the bag, the iiaps c c with the opposite thereof, and that the narrow strips ff are integral with the two remaining sides of the bag, whereby when said parts are 7 5 united in the manner described a strong' and durable end or base is formed, which effectually and securely closes one end of the bag.

The base is creased on diagonal lin-es h, which radiate from the center of the base to- 8o ward the four angles or corners thereof.

By creasing the base of the bag in diagonal lines h (see Fig. 5) and two opposite sides of the same, the bag may be folded to occupy but very little space.

In order to open a bag ot' this construction, the hand is inserted into the mouth of the same and the base pressed out evenly, at which time the bag assumes a rectangular appearance--such as shown at Fig'. 4. on the 9o drawings. l

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent,

A paper bag having the two small iiaps c c 9 5 formed integral with one of the sides thereof and cemented together to form one-half of the base of said bag, a larger flap, b, equal in :wen to the two flaps c C, and made integral with the opposite side of the bag and eemented to said aps e, and the nzu'low strips ffntegrfd with the two remaining* Sides of the bag' :md arranged at right angles to said Haps b c c, said Strips j' f beingI cemented te the buse of the 1mg Fel-med by uniting' the flaps on the inner side of said base, substmh tally :1S and AE01' the purpose described.
